The princess wants the prince to go do something heroic instead of lying around the castle catching flies all day (he's now human but retains some froggy habits).

The prince wishes she wouldn't nag him and thinks he was happier back at his lily pad.

The prince encounters three witches on his wanderings and asks each to turn him back into a frog, so he can live happily ever after.

The third lives in a gingerbread house, appears to know Hansel and Gretel, and invites the prince in for dinner.

When she tells him how much she loves him and was worried about him, the prince kisses the princess, and their troubles are resolved with a different happy ending: they are both transformed into frogs.
